A strap tensioning assembly having a casing and a reel or a pair of reels. A dial rotates the reels to reel in a tension member on each reel. A first torque limiting clutch is provided between the first reel and the dial, such that a tension in the first tension member is limited.

An automatic strap retractor tensioner comprises a winding assembly (winding rod, coupling shaft with first/second coupling gears; the third contact surface of the first gear engages the first contact surface of the winding rod for motion transmission), a tightening assembly (tightening body with slidably mounted first stop plate at inner mid-portion, rotatably coupled to the winding rod and equipped with a protective rubber handle), a braking assembly (brake body with rotatably mounted first brake plate at inner bottom and slidably mounted second brake plate at inner middle), and a take-up assembly (on the brake bodys side, housing a coil spring connected to the winding rods second contact surface for strap retraction). Their coordinated action reduces excess strap, enables controllable retraction speed, and enhances safety and usability.

Swim goggles with a strap; and an adjustment mechanism. The adjustment mechanism including a body and a frame both together forming an outer casing of the adjustment mechanism, the frame including an actuator and a stop, wherein the strap is routed through the adjustment mechanism.

A fastening system for an object (e.g., a wearable such as footwear) is disclosed that includes a buckle assembly and a strap for adjusting tension. The buckle assembly includes a base and a slider engaged with the base. The strap includes an array of teeth to engage with a pawl formed on the base. The fastening system is configurable between an engaged condition and a released condition based on the positioning of the slider relative to the base.

A band includes a latch body that is movable by pulling a tab. The latch body extends through an opening of the band and secures with a pin located on a head-mountable device. The band can detach from the head-mountable device by pulling the tab, which actuates the latch body and removes the latch body from the pin. A spring (or springs) can bias the latch body toward the opening, causing the latch body to enter the pin. An applied force to the tab can overcome the biasing force provided by the spring(s), and move the latch body away from, and out of, the pin.
